. CONTROLLING-VALVE FOR MULTIPLE FUEL-SUPPLY PIPES.

Specification of Letters Patent.

Patented Jan. 6, 1920.

Application filed March 26, 1918. Serial No. 224,910.

Pipes, of which the following is a specification.

My invention relates to internal combustion engines, and has for its object to pro vide a valve for controlling the flow of liquid fuel from multiple fuel supplies, whereby a highly volatile oil may be used in starting and warming up the engine and another less volatile and more economical fuel introduced and jointly used with the highly volatile or the supply of the highly volatile oil shut off and the less volatile oil introduced after the engine is partially warmed and started.

A further object of the present invention is to provide a valve whereby the highly volatile fluid may be directed to the combustion cylinders without passing through the carbureter for an initial charge to start the engine during cold weather, and at times when the carbureter is filled with low volatilizing A further object is to provide a valve whereby water may be directed into and for use in the engine when the less volatile fuel is used, and which valve will be closed and drain itself when it is turned to allow highly volatile fuel to flow through the carburetor of the engine.

These and other objects which are apparent I accomplish with the device illustrated in the accompanying drawings in which similar letters and numerals of reference indicate like parts throughout the several figures and are described in the specification forming a part of this application and pointed out in the appended claims.

In the drawings in which I have shown a substantial embodiment of my invention Figure 1 is an elevation of the front portion of an automobile with parts omitted to show my valve thereon. Fig. 2 is an elevation of the device. Fig. 3 is a vertical section on line 3 3 of Fig. 5. Fig. 4 is an elevation showing a different view from that shown in Fig. 2. Fig. 5 is a plan view of the device with the valve turned to allow the less volatile fluid to flow. Fig. 6 is a transverse section on line 6 6 of Fig. 2. Fig. 7

is a section on line 7 7 of Fig. 4:. Fig. 8 is a plan of the indicating dial used in operating the device. In the use of an internal combustion engine, it is desirable to economize in the cost of fuel by starting and warming up the engine on high grade fuel, and then by introducing and using a cheaper fuel for the general use of the engine.

In the use of internal combustion engines I have found that increased power may be developed by using a small quantity of water with the,less volatile fuel such as distillate. Also that burned or partially burned carbon will accumulate in the cylinders of the engine and prevent full development of the power of the engine, and that when small quantities of water are used with the fuel in the engine it will be freed from such deposit of carbon. The presentinvention is to provide a valve and other coacting elements which may be easily and quickly attached to most engines now in use whereby the engine may be supplied with different or commingled qualities of liquid fuel as desired, and also to supply water or steam into the engine when the less volatile fuel is used, with a drain from the device to prevent inj ury from freezing, which drain is closed when the less volatile fuel is used and opened when the highly volatile fuel is used.

In the drawings the valve casing in shown at A. having a central bore 1. Pipe receiving lugs 2, 3, 4, 5, 6 and 7 are integrally formed on and radially extend from said casing, and each is centrally bored and externally threaded. The said bores are extended radially inward and open -.-into the said central bore 1. Four of said bored lugs are on one transverse plane and the other two are on another plane. A drain vent 18 is also bored on the last described, plane through the wall of said casing and which opens into said central bore 1. The inner wall of said casing A has two recesses 8 and 9 cut or formed therein which open into said central bore 1. The recess 8 connects with the bore in the lug 2 and the recess 9 connects with the bore in the lug 5. The valve stem 11 has a transverse diametrically disposed bore 12 on the plane of the bored lugs 2, 3, 1 and 5, and two similar bores 13 and 14 respectively on the plane with the bored lugs 6 and 7. The said casing A has shoulders at and 6 formed on its upper end and a pin 15 is radially Secured insaid valve stem 11 to engage with said. shoulders a d limit the rotation of said valve stem. The said valve stem 11 may be rotated by means of a rod 17, as limited by said pin 15 and the said bores 12, 13 and let brought into alinement with the different radial bores in said casing A. A pipe 28 is screwed on the said lug 2 and connects a highly volatile fuel tank B with said casing A. The pipe 16 is secured on the said lug 3 and connects the less volatile fuel tank, not shown, with the casing. The water pipe 19 is screwed on lug 6 and connects the water sup-ply with the casing A and the pipe 20 which is screwed on the lug 7 leads to the engine through the carbureter. A primer pipe 21 connects the said lug 4 with the intake manifold of the engine, whereby highly volatile fuel may be introduced into the engine for starting without it having to pass through the carbureter. The lug 5 is connected with the carbureterCand by partially rotating the said valve stem 11 fuel from either tank or from both may be directed to the engine through the carbureter. It will be seen that with the valve stem as shown in Fig. 6 and pin 15 against shoulder a the less volatile fuel will flow and the highly volatile fuel will be cut off, also the bore 13 will be in alinement with the bored lugs 6 and 7 and the desired amount of water will pass the valve and be introduced into the engine. By partially rotating said valve stem clockwise by means of the rod 17 and as indicated by the dial 22 to the position marked Gas thereon the bore 12 will be brought into alinement with the bored lug 2 and the highly volatile fuel will flow therethrough and through the recess 9 and bored lug 5 to the engine, and if the rotation is continued to the position marked PR of said dial the bore 12 will be in alinement with the bored lug 4 and the highly volatile fuel will flow through the bored lug 2, recess 8, bore 12 and bored h1g4 to the intake manifold of the engine for priming the engine. Vhen the said stem is rotated to the position marked Off 011 the dial 22 and the pin 15 against the shoulder b the flow of fuel will be cut off. When water is flowing through the bores in the lugs 6 and 7, and the bore 13 it will enter the engine through the intake manifold D where it will commingle with the less volatile fuel and aid in keeping the cylinders free from carbon as well as producing a mixture more desirable and with greater strength and aid in keeping the temperature of the engine lower; and with the valve stem 11 turned so that bore 14 is in alinement with the bores in lugs 6 and 7 the bore 13 will be in alinement with the drain bore 18 and all water will be drained from the device through said bore 18. The essential features of my device consist in having the fluid pass through and be controlled by one economical valve whereby the engine may be started by the use of highly volatile fuel and by simply turning the valve stem, a less volatile fuel may be used in the engine with water or steam if desired and which water will not freeze in the device during extremely cold weather.

Having thus described my invention I desire to secure by Letters Patent and claim 1. In a valve of the class described the combination of a casing having a tapered axial bore, and having recesses in its inner wall which open into said bore; centrally bored lugs integral with said casing and extending radially therefrom, and with the bore of each opening into the axial bore of said casing two of which bores open into said recesses; a transversely bored valve oper able in said casing the bores of which may be brought into alinement with the bores in said lugs in pairs to conduct liquid fuel from a highly volatile fuel tankto the cylinders of an engine or to the carbureter as desired, also from a less volatile fuel tank to the same carbureter and from a water supply to the carbureter as desired; and means to rotate said valve to open and close said bores.

2. In a valve of the class described the combination of a casing having a central axial bore and two recesses in its inner wall which open into said central bore; axially bored radially disposed integral lugs on said casing the bores of which open into said central bore two of which bores open into said recesses; other lugs on a different plane bored to connect with said central bore; a drain conduit from said central bore through the wall of said casing; a transversely bored valve operable in said casing the bores of which may be brought into alinement with the bores in said lugs, with one of said bores opening into one or the other of said recesses adjacent a lug when in alinement with the bore in the diametrically opposite lug.

In testimony whereof I have aflixed my signature.
